TYPOGRAPHICAL MACHINE Filed June 26, 1930 2 Sheets-Sheet 2 IN VEN TORPatented May 31,. 1932 UNITED STATES PATENT OFFICE RICHARD SE. IMEAD, OFQUEEN-S VILLAGE, NEVJ" YORK, ASSIGNOR LINOTYPE COMPANY, A CORIEOBATIONOF NEW YORK I TYPOGRAPHICAL .MACHINEE Application filed June 26,

This invention relates to typographical machines, such as linotypemachines of the general organization represented in Letters Patent ofthe United "States No. 436,582 to O. Mergenthaler, wherein circulating"matrices are released from a magazine in the order in which theircharacters are to appear in print and then assembled in line, thecomposed line transferred to the face of a mold, the mold filled withmolten metal to form a slug or linotype against the matrices whichproduce the type Characters thereon, and the matrices thereafterelevated and returned 7 through distributing mechanism to the magazinefrom which they started. More particu l arly, it'relates to machinesequipped with a plurality of magazines containing different matrix fontsand which are arranged to be moved upwardly and downwardly in'the machine to bring one or another into operative relation to the assemblingand distributing mechanisms. 7 A a In these machines, the magazines 'aremounted in such manner that they may be quickly removed and replacedbyother magazines containing different matrix fonts, it being customarytoapply to the base frame of the magazine to be removed a pair ofsupporting arms on which the magazine may slide forwardly whendisengaged from its base frame. f

It sometimes happens that'the magazines are prematurely disengaged fromtheir base frames, or improperly, placed thereon, so that they slide offwhen the supporting arms are not in position to receive them; and inthat case, the falling magazines are likely to cause considerable damageto themselves or to other. portions of the machine, as well as injury tothe operator. The present invention is therefore directed to certainimprovementsin machines of the class stated intended to lock themagazines inplace and to prevent their release except when thesupporting arms are in position to receive them, The construction andarrangement of thef'parts will best be, understood from the detaileddescription which follows. p l

. WVhile as above stated, the invention is in-- tended for use moreparticularly in machines 1930. Serial No. 463,836.

equipped with a plurality ofshiftablemagazines, it is also applicable tomachines of the single magazine variety. Referringto the drawings: IFigure 1 is aside elevation of a portion of a linotype machine equippedwith the invention; v V Fig. 2' is a similar view on a larger scale,showing the front portions of the magazines with their base frames andassociated parts, and indicating how the magazines are re moved; 3

Fig. 3 is a longitudinal sectional view on line 33 of Fig. 2; an'd R LFig. 4i is a fragmentary top plan View of the new automatic look at oneside ofthe magazine. i

The matrices are stored according to font in the superposedchanneledmagazines A,

three of which are shown herein but of which a greater or'less numbermight be employed if desired. The several magazines are re movablysupported upon separate base frames A conjointly constituting a shiftframe which is arranged to be moved'upwardly and downwardly in the fixedmachine frame in the well known manner to bring any selected magazineinto operative relation to the assembling mechanism B at the lowerendand the distributing mechanism (3* at the upper end; Each of themagazines is provided with a series of matrix releas ing escapements D'(Fig. 2) which, when the magazine is brought-into operative position,',I

are actuated under the controlof the key board mechanism in the usualway.

In the present instance, the two upper base frames A are pivotedat theirupper ends, as I at A toa pair of plates rising from the lowermostbaseframe, so that the base frames and their. respective magazines maybe separated or spread apart to permit the inde-' pendentremoval of anyselected magazine.

Southern, Serial No. 399,956,. filed October 7 16,1929,t0 whichreference maybe had for do tails if desired. When in use, the magazines55 1 of and fast toa transverse rock shaft F our frame to disengage itfrom the escapement bank preparatory to its removal or replacement, suchlifting means being preferably constructed to support the magazine inits elevated position and to guide it in a straight path as it is drawnforwardly from the front of the machine. I

As best shown in Fig. 2, each bankof escapements D is mounted in theusual manner in a supporting bar of frame D which frame is screwed orotherwise fastened to the lower end of the corresponding-baseframe A Asordinarily, the magazines are formed on their undersides 'withtransverseslots or openings to receive the escapement bars, the latter beingformed 'on their upper sides with grooves which extend across themagazine openings and constitute in effect continuations of the groovesin the bottom plates of the magazines. Such being the relation of theparts, it is apparent that before a magazine canjbe removed, it mustfirst be disengaged from its escapement bank. V

For this reason, each base frame is provided with a central magazinelifting and supporting plate E, which in the present instance issubstantially as long as thebase frame itself and which located in acorresponding groove or recess E formed in the upper side of the baseframe; VAt its upper end, the plate E ispivoted to the base framein theusual way, thus permitting it to be swung upwardly in lifting themagazine; and at its lower end, it is provided with stop shoulders Enormally engaged with the customary forward transverse rib a on theunderside of the magazine andwhich thus retain the magazine in place onthe plate when the latter is in its raised position. v

' The swinging of'the magazine lifting and supporting plate ofeach baseframe is controlled and effected by a cam 'orequivalent device Farranged near the lower end. therenaled the base fr'am e. Thecan1:F,.when turned upwardly by rocking the shaft F engages against thelower side of the plate'E,

the same from the base frame to a" position as indicated bydottedlinesin Fig.

2, in which condition the magazine can easily lbe removed from the baseframe. The cam is i'limitedgin its downward movementby a stop shoulderF?in thebottom of a recess-F in the base frame and against which the camrests in its lowered position.

The operation of the cam shafts F may be effected in any desired manner,but it is proposed to employ for the purpose the usual I magazinesupporting arms, G. As shown,

these arms G are provided with bosses G adapted to be applied to theopposite ends of the cam shaft F of any selected base frame, means-beingprovided, as will later be eX- plained, for keying the arms to theselected cam shaft, so that the magazine supporting arms may be readilyapplied to or removed from the required cam shaft and, when applied,serve as handles or cranks for turning it in one direction or the other.In the Open ative position of the magazine supporting arms shown by thedotted lines in Fig. 2, they rest at their inner edges upon the.oppesite ends of -the appropriateescapement bar D the armsbeing-provided with-pins D which enter corresponding apertures in the'escapement bar and p-reventtheir acci'r dental disconnection from thecam shaft,

. In removing a selected magazine, the supporting arms are applied tothe corresponding cam shaft F in a position substantially at rightangles to the magazine and are then drawn downwardly to thelr magazinesupporting position, which action-effects the turning of the cam shaftand the lifting-"of the magazine from the base frame as justdescribed.Themagazineis then slightly raised at its forward end to disengageitsfront rib a from the stop shoulders 15 and slid forwardly along theplate E onto the supporting arms. all as more fully describedin the -Mc-Namara Patent No. l,586,316. a

Coming now to the. present invention, it sometimes happens that thematricesprd. trude slightly from the forward ends of the magazines, andin shiftingthe base-frames downwardly to bring a selected magazine intooperative position, these projecting matricescome into engagement withportions of the assembling mechanism and arrest the downward movement ofthe particular magazine from whichtheyprotrude. When this happens, thecontinued downward movement of the corresponding base frame (which isnot arrested) will result in the disengagement of the magazine rib afrom the stop shoulders. E ofthe lifting plate, leaving the magazinefree to slide forwardly and downwardlyout of the machine. If this shouldoccur at a time when the magazine supporting arms G are not in properreceiving position on the machine (and they never are during themovements of the shift frame), considerable damage is likely tov becaused by thefalling magazine. For this reason, it is proposed to lockthe magazines in position upon their respective base frames so that theycannot be displaced therefrom except when the magazine supportingarmsare in place. To this.

end, the invention contemplates the application'of locking means H atthe opposite sides of the base frames, said locking means functi'oningnormally to maintain the magazines upon their base frames.

In the present instance, the improved looking meansis shown only inconnection with the uppermost magazine (the one which is the chiefoffender), although it may of course be applied to all of the magazinesif desired. As best shown in Figs. 3 and 4, the locking means is"preferably located at each side of the base frame A and comprises asupporting plate H secured to the base frame as by screws H or othersuitable fastening means, and a latch member H pivoted to the plate H asby a pin H The inner end of the latch member H is provided with a smallshoulder H adapted to engage the adjacent edge of the lower plate of themagazine, and disposed between the latch member and the plate H is asmall compression spring H which normally tends to disengage the latchmemher from the magazine. The outer end H of the latch member extendstoward the adjacent magazine supporting arm G and has a relatively flatbottom surfaceH at one side of which is a slight bevel H Operative belowthe outer end 1H of the latch member is a cam F which may be integralwith a collar F secured to-the shaft F by a transverse pin F The collarand cam are mounted on the shaft at'the outer side of the base frame andare provided with teeth or keys F adapted to seat in grooves or keywa-ysF formed on the inner face of the supporting arm boss G Thus, the collarF 7 with its teeth or keys F constitutes the connection by virtue ofwhich the attached arms G rock the shaft for raising and lowering themagazine supporting plate E.

The cam F is provided with a high point F which is adapted alternatelyto engage and disengage the lower surface H of the latch 'member in suchmanner that, as the shaft. is rocked to lower the cam F, said high pointF will act upon the outer endH of the latch member and lock it in itsengaging position with reference to the magazine;

When, however, the shaft is rocked in the opposite direction to swingthe cam F upwardly and thereby to raise the magazine lifting plate: E,the cam F will release the latch member, leaving it free to be swunginto its disengagedposition by the compression spring H. The shaft Fwill, of course, only be rotated by the magazine supporting arms G, andtherefore'it will be clear that the locking means is under the controlof the magazine lifting meansand-can not be re leased until thesupporting arms are swung downward into position forreceiving themagazine from theb'ase frame.

It is believed that the operation of the parts will be entirely clearfrom the foregoing description. However, to. recapitulate,

assembling mechanism B. In this condition,

the lifting cams F are in their lowermost positions within the baseframe recesses F and the cams F 6 are in their lockingpositions,maintaining the latehmembers H in engagement with the opposite edges ofthe magazine, and thus firmly holding the magazine on its base frame.If, now, it is desiredto remove the upper magazine A (assuming it to bein position for removal as it is in'Fig. '1), the magazine supportingarms Gare applied to the ends of the shaft F as shown by the full linesin Figs.- 2 and 3, and are then swung downwardly to the dotted linepositionindica'ted in Fig. 2, thereby rocking the shaft. In the initialmovement of the shaft, the cams. F disengage the latch members H torelease the magazine from its base frame, andthereafter the contlnuedmovement of the 1 shaft causes the cam F to swing the plate E upwardly,lifting the magazine to disengage it from the escapements. The magazineis then free to he slid forwardly onto the supporting arms and removedin the customary way; In substituting a new magazine, the aboveoperations are simply reversed, that is to say, after sliding the newmagazine backonto the lifting and-support ing plate-E, thesupportingarms G are thrown upwardly to lowerthe magazine into engagement with theescapements, andqin the final movement of the rock shaft F the cams Fact against the lower surfaces H'- and H to move the latchmember H? intotheir locking positions. i l

In the accompanying drawings, the invention has been shown merely in:preferred form and by way of example'and as applied to a machine of theclass statedybut obviously many modifications and alterations may bemade therein without departing from the spirit of the invention- Forinstanoe','the' invention in its broader aspects is not limited tomachines in which the magazine must'firs t be disengaged from itsescapement bank before removal, but isalso applicable to ma chines inwhich the esoapementsare carried by the magazine. Moreoverythe inventiondoes not require that the release of the. magazine latches be efiectedby a rotary move ment of the magazine supporting arms after theirattachment to the base frame, but con; templates as well the release ofthe magazine latches by the direct application of the mag-' azinesupporting arms to the basefra-me. These and other changes will readilysuggest themselves to those slrilledin the art, and it should thereforebe understood that the inembodiment except in so far as such limitationsare specified in the appended claims.
